VIDEO: Nicki Minaj unleashes expletive tirade against Mariah Carey

New 'American Idol' judges Mariah Carey and Nicki Minaj have been playing down rumors of a feud since the duo signed on to the singing show last month. 

But a new video has surfaced showing things are getting a little heated on the judges bench.

During auditions in Charlotte, NC on Tuesday, Minaj unleashed a tirade of expletives apparently directed at Carey. 

TMZ published the video that features a furious and pink-haired Minaj shouting: 

"I told them I'm not f*ckin' putting up with her f**kin' highness over there."

Mariah can be heard saying, "“Oh why, WHYYYY .do I have a three year old sitting around me?”

Carey continues, "I can’t see my kids, because you decided to act like a little crazy b*tch and go all around the stage.”

Minaj also reportedly said she was going to "knock out" Carey but sources told TMZ that it was said off camera.

According to CBS, the feud was sparked by a disagreement over a contestant's performance. 

It's not the first time the pair of divas have worked together. Minaj and Carey collaborated on a remix of Carey's song "Up Out My Face" in 2010.

In September, Carey tried to shut down rumors that she and Minaj were already fighting, saying it was too early for things to get feisty.  "A feud takes a little longer to happen," she said, according to CBS News. 

Minaj agreed, saying the new judging panel is "getting along wonderfully, darling."
